Gowther. Gowther is a member of the Deadly Sins who bears the Sin of Lust, symbolized by the Goat symbol tattooed above his breast; he is an androgynous and bespectacled bookworm with pink hair who originally clad himself in a massive suit of armor Merlin designed to stabilize his power due to his unstable mind.
Gowther is a literal puppet created by a powerful demon and former member of the Ten Commandments who is the original Gowther.
